Water containing car fuel

ABSTRACT

Emulsions of mineral automobile fuel, such as gasoline and diesel oil, and containing at least 77 percent by weight of water, are described as a usable motor fuel. When vegetable oil is worked into the mixture, the automotive fuel can contain a percentage of water that can vary over a wide range. 
     The advantages in using fuel mixtures are lower fuel consumption, lower CO2 emissions, affordable automobile fuel, and a lengthening of the period for which the increasingly scarce reserves of mineral oil will be available.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an emulsion of water, a car fuel, suchas petrol, diesel oil or a type of vegetable oil and an emulsifier.Emulsions can be used as a new car fuel and may contain at least 77percent water by weight.

2. Brief Summary of the Invention

Object of the invention is to provide a payable car fuel that pollutesless than the usual fuels, to be realised by mixing water, at least inan amount up to 77 percent of the mixture weight, a usual car fuel andan emulsifier.

DETAILED DESCRIPTION OF THE INVENTION

This invention concerns an emulsified mixture of water with a motor fuelsuch as gasoline or diesel, and also concerns an emulsified mixture ofvegetable oil. Emulsions can be used as motor fuels. The addition ofwater to gasoline is known in the United States where the fluid known as“dry-gas” is added to the gasoline to mix the water present in the tankwith the gasoline to form a useable fuel. This concerns only smallquantities of water.

The Austrian patent in the name of Gerhard Auer Int. WO 95/25154,predominately describes the creation of alcohol-water andgasoline-diesel-water emulsions containing less than 70% water byvolume.

Furthermore, the American patent U.S. 2004/0121202 A1 gives thecompositions of emulsions for improving fuel cell functioning.

The American patent U.S. 2004/0005622 A1 describes an emulsion thatimproves the combustion of carbon particles. It has been shownexperimentally that mixtures containing by weight only 20 percentconventional mineral automobile fuel and 80 percent water can be used asautomobile fuels.

Characteristic of the emulsions according to this invention is also thatthe quantity of fuel can be as low as 23 percent of the total weight ofwater and fuel, which means that the water forms more than 77 percent.

When vegetable oil is mixed with mineral fuel water and emulsifier, thepercentage can vary over a wide range.

An example of a successful automotive fuel combination is an emulsionconsisting of 10.7 percent gasoline, 19.3 percent vegetable oil and 70percent water. Mixtures with more vegetable oil are also suitable forusing as a motor fuel. Assuming that gasoline, octane, has a carboncontent of 82%, this implies that the amount of CO2 emitted by themixture is only 324 grams per kilogram of emulsion. This is a 90%reduction of emissions compared to the use of gasoline alone.

Emulsions that separate can be reconverted to homogeneous fuel bystirring or shaking.

Assuming a mixture of 80% water and 20% gasoline, leads to the estimatethat the engine cylinder pressure can rise to more than 80 kg/cm². Thisis higher than the pressure occurring in normal gasoline engines.However, the ignition temperature is lower than in gasoline engines.

The advantages in using fuel mixtures are lower fuel consumption, lowerCO2 emissions, affordable automobile fuel, and longer use of theincreasingly scarce oil reserves.

1. Emulsions of water and fuel, such as gasoline, diesel oil, and oil,can be used as fuels in motors, with the characteristic that the watercontent is more than 77 percent of the total weight of the emulsion. 2.An emulsified mixture of water, a mineral automotive fuel and avegetable oil can be used as an automotive fuel.
